Google has likely been determining the outcomes of upwards of 25 percent of the national elections worldwide since at least 2015. This is because many races are very close and because Google’s persuasive technologies are very powerful.
In the weeks leading up to the 2018 election, bias in Google’s search results may have shifted upwards of 78.2 million votes to the candidates of one political party (spread across hundreds of local and regional races). This number is based on data captured by my 2018 monitoring system, which preserved more than 47,000 election-related searches on Google, Bing, and Yahoo, along with the nearly 400,000 web pages to which the search results linked. Strong political bias toward one party was evident, once again, in Google searches.
